The OPA593DNTR is a high-voltage (85 V), high-precision, wide-bandwidth (10 MHz), high-output-current (250 mA), unity-gain-stable power operational amplifier from Texas Instruments, packaged in a 12-pin WSON (DNT) housing measuring 4.00 mm x 4.00 mm with an exposed thermal pad. Operating from a single 8 V to 85 V or dual ±4 V to ±42.5 V supply, this CMOS-architecture device delivers laser-trimmed offset voltage of ±20 µV typical with ±0.4 µV/°C drift, eliminating calibration requirements while providing programmable current limit, mux-friendly inputs, rail-to-rail output, and comprehensive diagnostic flags for overcurrent and overtemperature conditions across -40°C to +125°C operation.
Applications
The OPA593DNTR is primarily designed for semiconductor test and manufacturing equipment, where it serves as a precision voltage and current source in automated test systems for wafer-level device characterization. Additional applications include programmable DC power supplies with digital control interfaces, LCD panel test equipment requiring high-voltage pixel driving, CT and PET scanner subsystems for medical imaging with high-precision analog control, piezoelectric actuator drivers demanding high voltage with capacitive load handling, VCOM drivers in display systems, automotive test instrumentation, ATE pin electronics, and general-purpose high-voltage amplification in industrial process control where 85V operation with 250 mA drive capability and diagnostic intelligence are essential requirements.

Frequently Asked Questions
Q1: What is the supply voltage range of the OPA593DNTR?
The device operates from a single 8 V to 85 V supply or dual ±4 V to ±42.5 V supplies, with absolute maximum rating of 93 V.
Q2: How is the current limit programmed?
An external resistor (RCL) connected between ILIMIT pin and V- sets the limit per the equation (3.687 V x 4000) / (56.7 kΩ + RCL) mA, or a voltage source can be applied to the ILIMIT pin.
Q3: What package thermal considerations apply?
The thermal pad is internally connected to V- and must be soldered to a PCB connected to V- even in low-power applications, with RθJC(bot) = 4.3°C/W requiring proper thermal via design.
Alternative power amplifier models
